LED breathing

Twin Op-amps generate a ramp-up/ramp-down output which gives the appearance that the LED is "breathing" and allows the user to pace their own breathing with the light.

why not doing that symetrical ramp-up/down? Changed the OpAmp output configuration cause the default one doesn't fit at all to the rest of the circuit. http://everycircuit.com/circuit/4946978499461120

Thanks for that! Yep I missed that detail. Actually pulled this circuit off a board I saw online and attempted to fit on a breadboard. But I am having difficulty with controlling the amplitude. The LED should go dark momentarily through the cycle but instead it barely dims.
